TOALL WHOM ITVMAY OONCERN:

Be it known that I, C. E. MURRAY, of Sugar Valley, in the county ofClinton, and State of Pennsylvania, have invented a new and improvedHorseiRake; and I do hereby declare that the following is a full, clear,and exact description thereof, which will enable those skilled in theart to malte and use thc same, reference being had to the accompanyingdrawings, forming part of this specification.

This invention relates toa new and improved revolving wire-toothhorse-rake, and it consists in a peculiar means employed for holding therake, and revolving the same at proper intervals, in order that it maydischarge its load, and also in a certain means to allow a vertical playto the teeth, to admit of them conforming /to the inequalities ofsurface over which they may pass. A

In the accompanying sheet of drawings* Figure 1 is a plan or top view ofn1y,invention.

Figure 2, a side sectional View of the same, tak-en in the linea: a',fig. 1.

Similar letters of reference indicate corresponding parts.

A represents an axle, having a wheel, B, on each end of it, and twoarms, C C, projecting from its rear side, to serve as bearings for therake-head D,'the latter being allowed tolturn freely in the former.

.This rake-head is provided with two sets of teeth, E E', which areconstructed of wire, and curved in the -usul form, as shown in g..'2,one'set of teeth projecting from the shaft in a direction reverse to theother set.

On one'end of the rake-head D there is attached a ratchet, F, providedwith two teeth at opposite points, and is a pawl, which engages withsaid ratchet, said pawl working on a pivot at a, and having a spring',Ib, bearing against it, the spring having a tendency to keep the pawlengaged with theyratchet.

The rear end ofthe pawl G is provided with an oblong slot, c, and isconnected to a rod, H, by a pin, cl, which passes through the slot c.

The front end of the rod II is attached to an arm, I, 'which is securedto one end of a shaft, J, the latter having its hearings e on afoot-board, K, the rear end of which is permanently secured to the axleA, and the front end supported by spiral springs f, on rods fx fX,attached to the thills L L, said rods passing through the foot-board K,and. serving as guides for the same, as will he fully understood byreferring to fig. 2.

The arm I has an eye, y, attached, through which a spring, h, passes.

This spring. is secured to the foot-hoard K', and has a tendency tothrow the arm I backward. in the direction indicated by arrow 1, (seefig. `2.)

To the extreme end of the rake-head, near the ratchet F, there issecured a plate, M, having an oblong slot, z', made in it, with a notchor recess, j, at each end of the slot, (see fig. 2,) and N'is a rod, thefrontend of which isiscrewed into a har, O, the latter being secured toand projecting'from .the arm I. r

The rear end of the rod N has a pin, It, projecting from it, whichpasses through the slet z'.

The rake is retained in position by the` pawl G, which engages with theratchet F, the pawl G, and rod II, holding the arm I forward, andkeeping the spring 7L depressed.

While the rake is`thus held or retained in position, the lower set ofteeth, E, rake up the hay, and when a suiicient quantity of hay has beengathered by them, the operator, -by pressing his foot upon a troadleattached to shaft J,forces back the rod II, therod N yielding or giving'sufficiently to admit of the rod vII forcing down the rear end of thepawl G, so that the front end of the same will'be raised out from theteeth of ratchet F.

When this is done, the spring instantly forces back the arm I, and thekrod N acts against the plate M, turning: it and the rake-head D a halfrevolution, in the direction indicated by arrow 2, so as to bring theset of teeth E down to a working position, where they are retained bythe 'vpawl Gr, which engages with the other teetl of ratchet-F.

After each half revolution of the rake, the arm I is moved forward andthe spring h depressed bythe driver actuating a treadle of shaft J, therod N, by this movement of the arm, heing drawn forward, so that the pinIc of said rod may catch into the forward notch or recessj, of slot Theseveral parts are then in n condition to ad'mitof another halfrevolution of the rake "being,r made, when required.

By having thefoot-'nonrd K. resting on springs Connected with thethills, the rake-teeth areallowod to rise and fall, to conform to theinequalities of surface over which they may pass.

By this means the teeth are prevented from being bent or undulystrained.

claim as new, and desire to secure. hy Letters Patent-` 1. The rake,provided with two sets of teeth, E E, and hung at the rear of the axleA, as shown, in coinbination with the ratchet F, pan'l G, rod H, arm Ion shaft J, spring L, and the rod N, and slotted plate M, all arrangedto operato in the manner substantially as und for the purpose set forth.I

2. The resting of the front end of the foot-board'K on spiral springs f,which rest on the thillsiL L. substantially in the manner as and for thepurpose set forth. Y Y

The above specification of my invention signed by me, this 17th day ofDecember, 1867.
